| Abstract: | The vapor‐phase polymerization of pyrrole to form conducting polypyrrole (PPy) films was applied to coat flexible poly(ethylene terephthalate) (PET) fabrics. A PPy‐coated PET fabric surface resistance of 200–20 000 Ω□?1 was obtained. The polymerization conditions, such as the concentration of oxidant and the reaction time and temperature, were systematically investigated. The coated fabric samples exhibited increasing temperatures when subjected to a fixed DC voltage. This result indicates the potential of these PPy‐coated fabric materials for heating applications.
